Avatar/ all: Upgrade structure from Start

In general master specialties start with their node conversion spell and often a certain bonus. Nearly all spells were changed slightly. This mod does not add units and the summon spells are there as a template for the additional mods. This means these are not linked yet properly.

The new class (Blood Magic) is very battle and tactical combat focused.
